2.4.2 Installed user base

The number of Tivoli Storage Manager servers installed for a particular platform
is a consideration. At the time of writing, there are more Tivoli Storage Manager
servers installed in Windows and AIX platforms, compared with the other
choices.
2.4.3 Cost
Cost is a very dynamic area to discuss in a static manual, so we only generalize
here. Check for special promotions and other discounts before committing to
acquiring a particular platform configuration.
Cost is further subdivided into platform costs and Tivoli Storage Manager
software license costs. Platform costs include the cost to acquire all the
hardware and software to run the platform exclusive of the Tivoli Storage
Manager software license. It ranges from low for a Windows system to high for
zSeries. The high cost of installing a new zSeries system usually precludes it
from being selected to run a Tivoli Storage Manager server exclusively.
However, if this platform is already in use, it can be an economical choice,
particularly if there is considerable in-house expertise on this platform available.
Tivoli Storage Manager license costs vary somewhat, with Windows costs being
the lowest, followed by Linux, AIX, HP-UX, Sun Solaris, and iSeries costs. All of
these are one-time charges to purchase the product. zSeries licenses are
available for a one-time charge or as a monthly license fee. You may want to
calculate the break-even point.
Tivoli Storage Manager server costs include a license for only one client by
default. To manage more clients, more client licenses must be purchased. The
actual client code is free to download. Under the current pricing model, Tivoli
Storage Manager is sold as a per-processor fee for either a server or client
